Do congestive heart failure and nausea mean the end is near?
The nausea could be very concerning, but then again it might not be related to your father's heart failure at all. Fatigue and tiredness are typically symptoms of very severe heart failure, but they don't necessarily mean the end is near. Still, I'd recommend that your father be evaluated by his doctor, to see if other medications might help.
Just a bit on insight- My Mother had it for 15 yrs and died with cancer. I would not as a consequence be too concerned if I was diagnosed with heart failure- it is usually a long term thing it seems to me as I know of another case that is some 15 yrs also. But he will not likely want to skip a rope and that is ok. I am not but an observer so do not take this as "Gospel"! God Bless you and your Father.
I do not know what to say at this point, I know that his heart is very weak, I know that he has Vasular Caridor problems, He has seizures, And he has sleeping disorders. He was just discarged from hospital, With congested heart failure. Can not keep his oxycen level above 80 lits.
